Outdoor wood-plastic composite floor

China has the world's largest construction market, and the unit energy consumption of building area of 2 to 3 times the developed countries, building energy consumption accounts for 27% of the energy consumption of the whole society, wall materials and doors and windows are the main factors affecting the building energy efficiencyone. Liao, president of the China Plastics Processing Industry Association, said that the potential applications plastic building energy efficiency market in China, not only a large number of on behalf of the steel, and wood, but also has energy-saving materials, ecological protection, improving the living environment to improve the function and quality of construction. reduce building weight, convenient construction superiority. He explained that the Ministry of Housing and Urban building energy efficiency overall objective: to 2010 new construction in cities and towns throughout the country to achieve 50% energy saving. Provide reliable quality, excellent performance of the new plastic wall materials and energy-saving windows and doors for energy-efficient buildings, both the burden shouldered by the plastics industry, but also provides a huge space for the development of the industry.

Polyurethane (PU) rigid foam is recognized worldwide as the best insulation materials, construction is simple and cost-effective. Studies have shown that building every 1 kilogram of polyurethane material, equivalent to a decrease of 755 kg of CO2 emissions in the average life of.
It is understood that the PU rigid foams for thermal insulation performance is superior, the lowest thermal conductivity of organic and inorganic insulation materials, and excellent mechanical properties, can withstand a wide temperature range and high-humidity conditions of wind, impact a variety of loads. The material also has a certain toughness, not easy to produce cracking; excellent waterproof, separated steam performance, it is difficult to compare to other insulation materials. PU rigid foam as well as from the carbonization of self-extinguishing characteristics, which can reduce the rate of spread of flame. At present, the building insulation materials in Europe and the United States and other developed countries, about 49% of the polyurethane material, but the proportion in China is still less than 10%. To this end, Liao said, enterprises should actively research and development of low smoke, low toxicity flame retardant green polyurethane foam material, to win market opportunities.
Can be made of polystyrene foam (EPS), the continuous extruded polystyrene foam (XPS) insulation performance, as technically ripe for energy-saving building materials, mainly used in the construction of walls, roof,places such as windows, doors and ground. EPS, XPS foamed magnification up to 50 times, EPS98% of the volume of air, only 2% of the material, is a fixed air, shock, saving resources, excellent material, with an average load 5 tons per square meter. In addition, microporous plastic with excellent performance, fatigue life increased by 4-7 times 6-7 times higher impact strength than traditional insulation materials, to speed up the process of industrialization will be a major breakthrough in energy efficiency (insulation, thermal insulation) materials.
According to the the WPC Professional Committee of CPPIA vice president, chairman of Beijing of Futuresoft Technology Development Co., Ltd., Dr. Song Weining, phenolic foam in recent years developed a new type of material, its flame resistance, low smoke and high temperature stable performance, the adiabatic insulation, sound insulation, easy molding, better durability, and is known as the third generation of emerging insulation materials. In the next few years, phenolic foam, the output value will be the average annual growth rate of 20%. Outdoor wood-plastic composite floor
China is the world's first large windows and doors production and user countries, doors and windows of the demand growth rate of 11% per annum in the doors and windows of the annual new housing demand of more than 500 million m2, while the existing building renovation demand for energy-saving windows and doorsover one billion square meters, Fenestration annual total consumption is equivalent to four times that of Europe.
It is understood that the plastic doors and windows, energy efficiency is very prominent, with insulation, sound insulation and moisture characteristics. In the heat transfer, the thermal conductivity of plastics only steel 1/360, 1/1250 of the aluminum, has good insulation properties. At the same time, the plastic doors and windows profiles are multi-chamber structure, make full use of the thermal insulation properties of air, and further reduce the thermal conductivity of the material as a whole. In airtight performance, the plastic door sash feed or fan material between by melt welding, window frames, sashes are a whole, there is no gap between the horizontal and vertical material eliminate the air through the corner of the cross feed and vertical feed stitching possibilities.
According to information available, the plastic profile manufacturing has great advantages in energy saving, from raw materials to produce the whole process of the product point of view, the production of one ton of plastic profile than the production of one ton of aluminum saving 10,000 kwh left and right, and more to produce 1 ton of plastic profile can save 3.6 tons of coal, to reduce the CO2 emissions of 9.43 tons, 30.6 kg to reduce the emission of sulfur dioxide gas, to reduce the emission of nitrogen oxide gases 26.64 kg. best outdoor wood plastic floor
